** 2) Automatic Recognition of Transaction Statements and Screenshots

Uploading transaction statements (PDF), brokerage holding screen captures, or CSV files automatically retrieves the stock, quantity, and acquisition price. You can register multiple files at once, and holding screens displayed in US dollars are converted to Korean Won using real-time exchange rates.
